Unexplainable pain and heartbreak

My sister Dana Foster is a 30 years old angel! She left behind two amazing boys Jamie(11 years old at the time) and Jaxon(2 years old at the time turning 3 the day after his mommy was killed).  She was murdered by her abusive boyfriend of 8 months. It will be hard every single day for our lives without her. But her spirit and memories will live on through everybody she touched!
